Predictive value of inferior vena cava respiratory variation index for hypotension in elderly patients undergoing radical resection of cervical cancer under general anesthesia
Objective To investigate the predictive value of inferior vena cava respiratory variation index(IVC-RVI)for hypotension in elderly patients undergoing radical resection of cervical cancer under general anesthesia.Methods The clinical data of 107 elderly patients with cervical cancer who underwent radical resection of cervical cancer under general anesthesia in Lianyungang First People's Hospital,Jiangsu Province from September 2020 to May 2023 were retrospectively analyzed.They were divided into hypotensive group and non-hypotensive group according to whether hypotension occurred within 48 hours after operation.Clinical data were compared between two groups,and the related factors affecting hypotension in elderly patients underwent radical resection of cervical cancer under general anesthesia were analyzed;the predictive value of IVC-RVI for hypotension in elderly patients underwent radical resection of cervical cancer under general anesthesia was determined by receiver operating characteristic curve.Results Thirty-six(33.64%)of 107 elderly patients underwent radical cervicectomy under general anesthesia had hypotension.The proportion of hypertension,pulmonary capillary wedge pressure,central venous pressure,and IVC-RVI in hypotension group was higher than those in non-hypotension group(P＜0.05),and the proportion of preoperative vasoconstrictor drug use was lower than that in non-hypotension group(P＜0.05).Hypertension and IVC-RVI were risk factor for hypotension in elderly patients underwent radical cervicectomy under general anesthesia(OR=2.881,3.235,P＜0.05),and preoperative vasoconstrictor drug use was a protective factor(OR=0.334,P＜0.05).The sensitivity,specificity,and area under the curve of IVC-RVI for hypotension in predicting hypotension in elderly patients underwent radical resection of cervical cancer under general anesthesia were 88.89%,87.32%,and 0.869,respectively.Conclusion IVC-RVI has high value in predicting hypotension in elderly patients undergoing radical resection of cervical cancer under general anesthesia.
